Note 1. For servo system controllers which are available with this, contact your local sales office.
2. It is not available with MR-J4W2-_B servo amplifiers.
You can switch gains during rotation/stop, and can use input devices to switch gains
during operation.
This function suppresses vibration at the arm end or residual vibration.
This is a filter function (notch filter) which decreases the gain of the specific frequency
to suppress the resonance of the mechanical system.
When a load is mounted to the servo motor shaft, resonance by shaft torsion during
driving may generate a mechanical vibration at high frequency. The shaft resonance
suppression filter suppresses the vibration.
This function provides better disturbance response in case low response level that
load to motor inertia ratio is high for such as roll send axes.
Gain adjustment is performed just by one click on a certain button on MR
Configurator2.
MR Configurator2 is necessary for this function.
This function makes the equipment continue operating even under the condition that
an alarm occurs.
The tough drive function includes two types: the vibration tough drive and the
instantaneous power failure tough drive.
Enables to avoid triggering [AL. 10 Undervoltage] using the electrical energy charged
in the capacitor in case that an instantaneous power failure occurs during operation.
Use a 3-phase for the input power supply of the servo amplifier. Using a 1-phase 200
V AC for the input power supply will not comply with SEMI-F47 standard.
This function continuously monitors the servo status and records the status transition
before and after an alarm for a fixed period of time. You can check the recorded data
on the drive recorder window on MR Configurator2 by clicking the "Graph" button.
However, the drive recorder will not operate on the following conditions.
1. You are using the graph function of MR Configurator2.
2. You are using the machine analyzer function.
3. [Pr. PX30] is set to "-1".
4. The controller is not connected (except the test operation mode).
5. An alarm related to the controller is occurring.
This function calculates the power running energy and the regenerative power from
the data in the servo amplifier such as speed and current. Power consumption and
others are displayed on MR Configurator2 in the system of SSCNET III/H. Since the
servo amplifier sends data to a servo system controller, you can analyze the data and
display the data on a display.
From the data in the servo amplifier, this function estimates the friction and vibrational
component of the drive system in the equipment and recognizes an error in the
machine parts, including a ball screw and bearing.
MR Configurator2 is necessary for this function.
This function improves the response delay occurred when the machine moving
direction is reversed. This is used with servo amplifiers with software version B4 or
later. Check the software version of the servo amplifier using MR Configurator2.
